I am making a set of functions for my own use in a console-based program. I want to essentially create a "text based text box" where I can read each character the user sends as soon as they press the key. For example, with cin, the user enters a string. Now, if the string is too big to be held in the array you have them put it into, the program will crash. So I want to make an input function that gets each character one at a time, reads them, decides what to do with them, and THEN allows another character to be entered, like with getche in conio.h I would use conio, except I want to develop this on my linux box and conio is specifically for windows, as far as I can tell. Thanks.

you could use std::string, it would be easier

#include <iostream>#include <string>int main(int argc, char *argv[]){  std::string input;    // this will stop at the first space  std::cin >> input;  std::cout << "Your input was: " << input << std::endl;  // this will get a whole line  std::getline(std::cin, input);  std::cout << "Your input was: " << input << std::endl;  return 0;}

hope that helps !

You could use getch().

maybe something like

for (double x = 0; x < SIZE_OF_ARRAY - 1; arr[x++] = getch());arr[SIZE_OF_ARRAY] = '\0'

? That should fill up every element in the array, and store it all as a string (char array, similar thing).

Is that what you wanted?

perhaps something like

bool y;char x;While (y) {x = getchar();y = (x != '\n'))

Would be better?
